*2.21 (Financial application: calculate future investment value) Write a program that reads in investment amount, annual interest rate, and number of years, and displays the future investment value using the following formula: futureInvestmentValue = investmentAmount * (1 + monthlyInterestRate)numberOfYears*12 For example, if you enter amount 1000, annual interest rate 3.25%, and number of years 1, the future investment value is 1032.98. Here is a sample run:

import java.util.Scanner;
 
public class ProgrammingEx2_21 {
 
 public static void main(String[] args) {
  Scanner input = new Scanner(System.in);
 
  System.out.print("Enter investment amount:");
  double investmentAmount = input.nextDouble();
  System.out.print("Enter annual interest rate in percentage:");
  double monthlyInterestRate = input.nextDouble();
  monthlyInterestRate = monthlyInterestRate / 12;
  System.out.print("Enter number of years:");
  double numberOfYears = input.nextDouble();
  double futureInvestmentValue = investmentAmount
    * Math.pow((1 + monthlyInterestRate / 100),
      (numberOfYears * 12));
  System.out.print("Accumulated value is " + futureInvestmentValue);
 
 }
 
}
